SubjectRE: [BUG] module_init_tools 0.9.10
Date
From
Dear Kai,

This is in relation to your suggestions to get a module working in 2.5
kernels.

After tweaking my Makefile, I managed to get it working for 2.5.59 but
now it no longer compiles under 2.5.64!

Here is my "tweaked" Makefile which compiled and loaded fine for 2.5.59.
Grateful if you could kindly suggest how to adapt it to 2.5.64 as I
really need to get it working. When compiling, vermagic.o can no longer
be found.

Many thanks.

Regards,
Se-Hsieng

Put something like the following into your your_driver/Makefile

---
KERNELSRC=/lib/modules/`uname -r`/build

all:
make -C $(KERNELSRC) SUBDIRS=$$PWD modules

obj-m := test.o

test-objs := test1.o test2.o
---


and then just do "make".

If your kernel source isn't pointed to by /lib/modules/`uname -r`/build,
override with "make KERNELSRC=/where/the/source/is"


HTH,

--Kai
